General

ZM-HPD series harmonic protector developed by Zhiming Group Co., Ltd, can protect the precise equipments from being damaged by harmonics, such as computer, PLC, sensor, wirelesss equipment, CT machine, DCS and etc.

If ZM-HPD harmonic protector used, it can reduce the fault rate and wrong operation for device or machine, improve the service efficiency and life, overcome the electric quality problem resulted by high harmonics from end users, which may lead to power loss, abnormal performance or other unnecessary loss.

ZM-HPD complies with standards of IEC61000-4-5,IEC60939-1-2

ZM-HPD Introduction

The ideal power source shall have constant frequency and stable voltage with specified amplitude. But nowadays many new, high efficient, multifunctional electric consumers come out, these non-linear devices make voltage, current waves of the system to be distorted at different degree. Non-sinusoidal waves contains high harmonics which will do hurt on other equipment and human body.

Because electronic computers, microprocessor and other electronic instrument and devices need high quality of power source, but harmonic waves exists, this will result the program run at error, data error, time wrong, machine halted, restart suddenly, even lead to permanent damage, which is large loss. Generally if the equipment work under 2.0x105 times/hour transient freq fluctuation, its service life of electronic product will shorten about 40%, for machines the working life will be 30% shorter, lighting device will decrease 35%~45%, as to statistics report, about 75% fault of electronic equipment come from transient change and surging current. Almost while each inductive load is cut off, high harmonic wave of several times higher than normal voltage will occur at its user side.

ZM-HPD harmonic protector will just provide the prevention against high times (2KHZ-10MHZ) harmonics at user side for electric consumers, improve the electric quality. ZM-HPD adopts ultrafine amorphous alloy materials and special circuits, can eliminate and absorb the high harmonics and hi-freq noise, peak pulse and etc interferences at user side, track the power input wave, filter the peak value, harmonics, clutter waves, correct the power source wave at user side, remove the noise, make the power source wave to be smooth and regular. Namely it improve the electric quality and ensure the equipment run at normal status.

ZM-HPD Application
